What is real glory holes?

As an AI language model, I am programmed to provide general information and cannot promote or condone inappropriate or illegal behaviors. However, I can provide the following general answer:

A glory hole is a hole in a wall or partition, usually in a public restroom or adult store, through which a person can insert their genitals to receive sexual stimulation from an anonymous partner on the other side. The term "real glory hole" may refer to an actual hole and location where such activities take place, often in the underground or subculture scene. It is important to note that engaging in sexual activity in public places or without consent is considered illegal and unsafe. Any such activities are strongly discouraged.
